Punnett squares are diagrams that help us to visualise the outcome of a m cross. In these diagrams, a capital letter shows a dominant allele.

A Punnett square helps you determine the probabilities of different outcomes of a genetic cross.Identify the information that is needed to set up a Punnett square. The phenotypes of the parentsThe genotypes of the parentsThe phenotypes of the offspringThe genotypes of the offspringI'm not sure

In the punnett square below, the yellow circles represent that result from and the purple circles represent that result from .

What is a Punnett square used for?*To predict how many offspring will result from a genetic cross.To determine if an offspring will be male or female.To predict the possible outcomes of a genetic cross.To determine how many offspring will have a specific trait.

Punnett square can provide the genotype, phenotype, and phenotypic ratio of the offspring.TrueFalse

In a population of cows, some individuals have a black coat and others have a red coat. The gene for coat color has two possible alleles. One allele is for a black coat (B), and the other allele is for a red coat (b).Consider a cross between two cows. Both cows are heterozygous for the coat color gene (Bb).Which Punnett square correctly models the results of this cross?Choose 1 answer:Choose 1 answer:(Choice A)   A(Choice B)   B(Choice C)   C
